Getting Started
The MSP-EXP430F5438 Experimenter Board is an evaluation board meant to evaluate the capabilities ofthe MSP430F5438 family of microcontrollers. Built to complement the MSP430's high degree ofmixed-signal integration, the Experimenter Board showcases external peripherals such a dot-matrix LCD,two-axis accelerometer, microphone, audio output, a serial USB connection and RF add-ons. Deliveredwith an example software project to help firmware designers understand how to program the new modulesof the MSP430x5xx family of devices, there is no better way to learn how to use the an MSP430F5438than with the MSP-EXP430F5438 Experimenter Board. This document details the hardware, its use, andthe example software.

Tools Requirements www.ti.com
An MSP430 Flash Emulation Tool (MSP-FET430UIF) or equivalent programming tool is required todownload code and debug the MSP430F5438. The JTAG programmer is connected to theMSP-EXP430F5438 Experimenter Board via the JTAG header located in the top center of the board. TheMSP430F5438 utilizes the standard 4-wire JTAG connection. For more details on the installation andusage of the Flash Emulation Tool, see the MSP430 Flash Emulation Tool (FET) user's guide (SLAU157 ).[3]
Texas Instruments' Code Composer Essentials (CCE) is an MSP430 integrated development environment(IDE) designed specifically to develop applications and program MSP430 devices. CCE Professional, CCECore Edition, and IAR Embedded Workbench can all be used to evaluate the example software for theExperimenter Board. The compiler limitation of 4 KB prevents IAR KickStart from being able to be used forthe evaluation of the example software.
The example software, titled "User Experience," is available online as SLAC227 . The User Experienceapplication must be loaded onto the MSP430F5438 that comes with the kit and is documented inChapter 5 . When compiled and run using an IDE, the APIs that have been included in the examplesoftware can be used to develop unique applications with the Experimenter Board. The APIs can serve asinterfaces to the internal hardware modules of the MSP430F5438 (for example, ADC12 or UCS) as wellas external peripherals and components (for example, buttons or an LCD). Chapter 5 describes the stepsrequired to compile and run the example software using Code Composer Essentials.
